lROTARY P'UMP.

I Speeication of Letters Patent.

Application filed August 19, 1912. Serial No. 715,797.-

To all whom may concern Be it known that I, ELIJAH H.'PEEKINs, a

citizen of the United States, residing at- Dinuba, in the county of Tulare and State 5 'of California, have invented new and useful Improvements in Rotary Pumps, of which the. following is a specification.

This invention relates to a deep well pump.

It is the object of this invention to provide a deep well pump of simple construction, whichis eiicientin operation,embodies the features of a balanced rotary pump, and is adapted. to be lowered into a .well casing to a point adjacent to or below the surface of the liquid to be pumped.

Another object is to provide a rotary pump in which the blade or runner-is disposed horizontally in a casing so constructed that the intake sect-ion is above therunner l and the discharge is from the underside thereof. j

Other objects will appear hereinafter. The invention primarily resides in'mounting a turbine or runner on the lower end of a vertical revoluble shaft, disposing the formed therein that the liquid to be pumped will be drawn into the housing above the runner and be discharged from the underthe invention as applied. Fig. 2 is a hori,

zontal section on thelline X-X of Fig. 1. Fig. 3 is a horizontal section on the' line Y-VY of Fig. 1.

In the drawings the well casing is indicated at A, and B represents a collar or `flange mounted on the interiorthereof at any suitable point. The liange B is beveled on its upper edge and is designed asa supf port for a runner housing consisting of' two parts'2 and 3, bolted together by means of bolts 4. The lowermost .portion 2 of the housing is beveled on its lower outer edge lto conform to the bevel on the flange B and rest thereon. The underside of the port-ion l 2 of the housing is open and is formed with shown. y The chamber 11 in the housing porside of the runner into the discharge column, and adapting the housing andthe runner; therein to be loweredrto a suitable point ay horizontal flange around this opening, to

which a flange coupling 5von a suction pipe G may be secured by means of bolts '7; the plpe 6 extending to a suitable point below the liquids in the well casing A. The upper side of the lower portion 2 of the housing 1s closed to separatev its interior from that of the upper portion 3 by means of a horizontal wall or partition 8, with the exception of a port 9, formed in the partition 8, which communicates with apassage 10 formed in the leadsupwardly in the housing,thence inwardly `and opens to the interior'of the portion `3 on its upper side through an .annular port 10; a' chamber llbeing formedin the portion 3 to which the passage 10 leads. The 'chamber 11 forms a casing for a tur. bine or runner- 12, which is horizontally disposed therein, and yis mounted on the lower end vof a vertical revoluble shaft 13 extending through a hub let on the portion 3 of the housing, whence vit leads upward to thel top of the well casing A and is connected to any suitable means for rot-ation not here tion 3 communicates on its upper side with the interiorl of the well casing throughv a discharge port 15 disposed in the portion 3 of the housing at a point opposite the intake passage 10 and to one side of the runner v12.

. Patented Jan. 7, 1913.

The blades of the runner 12 are so shaped` that when it is rotated it will act to create a suction downwardly on its upper side t0 draw the liquids to be pumped upward through the pipe 6 and passage 10, and downward through the port 10, then discharge it peripherally into the chamber 1l and force it into the well casing A through the port 15; the ldirection of llow of the liquid being indicated by thel arrows in Fig. l;

Formed on the upper end of the hub 14 is an outwardly extending flange 16, to which is secured a flange coupling 17 on the lower end of a pipe 18 bymeans of bolts 19. The

"pipe 18 surrounds the shaft 13 and extends' upwardly therewith to a point adjacentto the upper end of the well casing and` forms a guide for the shaft; bushings 20 being mounted in the couplings 21 joining sections of the pipe 18. The bushings 20 are formed of any suitable material and are held in place between the ends of adjacent sections of the pipe, as shown in Fig. 1. The pipe 18 is normally retained inv its centrallposi- 65 portion 3 of the housing. This passage 10 tion by. means ofv a centralizing device, (shown in detail in Fig. 2), whichY devlce consists of a pair of clamping members 22 and 22 which are designed to surround the pipe 21 and be clamped thereto by means of bolts 28. Mounted on the clamp member 22 is a pair of outwardly extending studs 24, the outer ends of which contact the inner face of the well casing A. Mounted on the clamp section 22 is a short stud 25 on which a sleeve 26 is slidably mounted. The outer end of the sleeve 26 normally contacts the inner wall of the well casing A and is retained in its outermost position by means of a helical spring 27 mounted withinthe sleeve 26 and bearing against the outer end of the stud 25. The spring 27 is of suiicient tension to retain the outer ends of the studs 24 in contact with the inner face of the well casing A. The 'centralizingv devices are clamped on the pipe 18 at suitable points throughout its len th.

n the operation of the invention, the shaft 18 is rotated in any suitable manner so as to revolve the runner 12 within the chamber 11 of its housing. The rotation of the runner 13 acts to -create a suction within the chamber 1l tending to draw the fluids in the well upwardlthrough the pipe 6, passage 10, and port 10', before described, and as indicated y the arrows in Fig. 1. The fluids thus drawn into the chamber 11 are discharged therefrom by the runner 12 through the port 15 and forced upward in the well casing A. Blades 28 are formed on the underside of t-he runner and extend in such a direction as to assist in the upward movement of the liquid. From the foregoing it will be seen that the runner 12 and shaft 13 are balanced; the suction created by the runner on its upper side and the weight of the column of water in the well casing A bearing against the underside of the runner 12 tending to lift the runner and shaft 13 and thereby counterbalance their weight to a considerable degree.

By this construction any simple bearing for supporting the shaft 13 may be employed at its upper end.

By forming the housing in the two detachable parts 2 and 3, they may be separated by removing the bolts 4 to give access to the runner 12; this construction also enabling the runner 12 being placed in position when assembling the parts. y

The runner housing is designed to be lowered into the well casing until it rests upon the iange where it is retained by its weight, combined with the weight of the pipe 18 attached thereto.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a deep -well pump, the combination with the well casing, of a flange on the interior thereof, a runner housing supported on.
